You’re Pinkie Pie!

It was all good in Equestria, before the infection, now known as The Graveyard Plague.

Applejack was one of the first infected, after saving her sister, Apple Bloom from an infected person.

However, AJ managed to kill the infected person, but she got bitten in the process, and she fled from Sweet Apple Acres, her home, and the barn.

Applejack got infected, but somehow after she got infected, Discord had saved her, from Fluttershy’s request.

Discord took the infection from Applejack, saving her but he had used some of his magic to make Applejack to be more powerful, more useful, and is immune to the infection now.

After that, Applejack woke up and found herself at Rainbow Dash and Pinkie Pie’s compound.

Rainbow was more serious, and less talkative, but Pinkie Pie, she was the same, or at least trying to be.

The compound was heavily stocked on food and water, due to Pinkie Pie since everyone knew how stocked she was due to her past job at Sugarcube Corner, which used to be a bakery.

There was other survivors there, and Rainbow was the leader of them, Pinkie Pie being the head of making food for everyone.

However, after maybe a month into the plague, Applejack and Pinkie Pie got into a relationship, and while Pinkie was as sweet and kind as ever, Applejack was more possessive, more aggressive to those who she found to be a threat.

One day, Pinkie Pie had just finished cooking food for everyone, and people was coming to the kitchen to get handed the equal share of food and drinks that they needed.

Applejack came in after everyone got their food and drinks, and everyone walked to their rooms, the doors opening and closing, and when Applejack walked in, she saw Pinkie Pie was washing pans and utensils.

Pinkie didn’t even notice Applejack had come in, so she was surprised when she felt Applejack wrap her strong arms around Pinkie’s waist, making her back press directly against Applejack’s front.
